In today's world, there is a huge advancement in the field of technology. Which made the internet as one of the primary sources of the communication channel. This leads to the development of several secure information-sharing protocols and applications for communication over the internet. These cybersecurity applications are guarding us against cybercriminals from stealing our sensitive data for Ransom or any other malicious activities. Still, there is a huge gap in the cybersecurity domain for such applications. In this research, our intention is to build a steganography-based application for secure communication of sensitive data. This application will hide the textual message inside the image file using the RSA (Rivset–Shamir–Adleman) algorithm. The encryption and decryption of the image contain a hidden message will be done through our application using current advance techniques.
